The 40mm VOG-25P, VOG-25M and VOG-25PM rounds are designed to be fired from grenade launchers attached to assault rifles and used to engage exposed enemy manpower at ranges up to 400 meters as well as manpower located on reverse slopes of terrain, inside open engineer installations and military equipment (vehicles, launchers, radars, etc). In addition, the VOG-25PM rounds provide an air burst of a grenade at a height of 0.5-1.5 m above the ground surface, which makes it possible to defeat enemy manpower located in trenches, ditches and other open engineer installations.
